CORRUGATING-MACHINE FOR CANS AND OTHER DEVICES.

Application filed April 29, 1918.

To all whom it may concern.

Be it known that we, VVILLIs J. BOYLE, S12, and FRANK R. 1)ALLMANN, bothcitizens of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented new and usefulImprovements in Corrugating-Maohines for Cans and other Devices, ofwhich the following is a specification. l

This invention relates to machines for corrugating cans and othercontainers and devices, and has for its object to provide an improvedmachine of the character mentioned which will be superior in relativesinr plicit'y and inexpensiveness of construction and organization,facility in use and control and in adaptation to varying conditions andclasses of work and service, and which will be positive and speedy andaccurate in operation, and durable, and generally superior in efliciencyand serviceability.

and the other end, as at 12, in a knock-down journal or hearing means 0,which, when suitably manipulated, permits the opening up or freeingofthe respectiveend of the shaft for passage therefrom of the work or canwhich is to be brought into position between the corrugating members Aand B so as to surround the corrugating member B, as clearly shown inFig. 5. The upper shaft 7 has its journal boxes 9 and 10 mounted to playvertically in suitable guides 11 in the frame 0, and adjusting means Dare provided for elevating or 10 wering such ournal boxes 9 and 10 ofthe shaft 7, to relatively space the shaft 7 from the shaft 8, all inaccordance with the workin organization of the corrugating members i andB, as hereinafter delineated. To that end screw shafts 13 and 14 havethread connection with such boxes 9 and l0, as at 15, and such shafts attheir upper end carry fixed miter gears 16 and 17 respectively, whichrespectively mesh with miter gears 18 and -19. upon a master shaft 20journaled as at QI-and 22 at and extending lengthwise of the frame C.The shaft 20 carries a hand wheel23 with a crank 24 whereby the shaft 20ma be re volved to operate the shafts 13 anc 14 and vertically adjustthe boxes 9 and 10 with the shaft 7 of the upper oorrugating member A.

E designates means for jointly driving the two corrugating member shafts7 and 8 to revolve the same and cause them to coact to corrugate the candisposed in part between them and passed on to the lower corrugatingmember B prior to the effective application to the shaft 8 of theknock-down hearing or journal means 0. Such drive means E may comprise asuitable train of gears, as disclosed, adapted to take power from anysuitable prime mover or transmission means. The knock-down bearing means0 comprise two separate angular lever members or hell cranks, 25 and 26respectively, which are respectively pivoted as at 25 and 26 inconnection with the respective end of the frame C, and the shorter armsof which are loosely connected in overlapping relation as at 27, so asto be capable of pivotal movement in common. The longer arms of saidlever members carry respectively journal members or bearing members 25and 26* which are adapted to be brought together to jointly surround andform a complete bearing or journal for the shaft 8 as at 12; a pivotallatch member 28 being connected with the bearing member 26" and adaptedto be brought into engagement with the hearing member 25 tends totemporarily hold such bearing or journal members in assembled relationto revolubly sustain the otherwise free end of the shaft 8.

The lever member 25 is provided with a rigid handle member 29 wherebythe two lever members may be jointlymanipulated to bring them intoassembled relation. ii. weight 30 loosely suspended from the point ofover-lapping loose connection at 27, of the lever member 25 with thelever member 26, exerts a constant tendency to disassemble the bearingmembers 25 and 26" and cause the same to swing apart upon their pivotalsupports at 25 and 26 The corrugating members comprise one or morecorrugating die sections 31, which are generally circular in crosssection, subject to modification in accordance with the design ofcorrugation to be produced in the use and application of such diesections, and having their ribs extending parallel with the axis ofrotation. These die sections are provided each with a central opening 32where by the same may be passed upon the shaft '7 or the shaft 8, andsuch die sections are held in place by collars 33 similarly applied tothe shafts, and the endmost of which, at corresponding ends of theshafts, are held fixedly in place by pins 34. The die sections upon eachshaft are held in assemblage at the other end of the shaft by a lock nutdevice 35 threaded on to the shaft. The collars 33 may be of anythickness, to be used as blanks in mounting the die sections upon theshafts, so as to hold in aggroupment the proper number of die sectionsas shall be proportionate to the depth of can or length of corrugatingzone ranging endwise of the shaft; and such die sections may be of anysuitable thickness and permit the outside dimension of a totalassemblage of die sections properly proportioned, reckoning lengthwiseof the shafts, to produce the desired corrugating effect upon the can orother device.

Means F may be advantageously provided for effectively centering the canupon the lower corrugating member, as B, or preventing the same fromlateral shifting and opposing rocking or instability o f the can orother device upon such lower corrugaling member. Said means may compriserollers 36 maintained in spaced relation and at opposite sides of theworking zone of the machine, slightly beneath the horizontal plane ofthe lower shaft 8. These rollers may be supported each upon anadjustably opposed frame, there being two sets of such opposed frames,vac-h frame comprising an upper member 37 and a lower member 38, looselyjointed together as at 39, and each provided with a collar 4L0, theupper collar surrounding a frame member ll and the lower collarsurrounding a frame member 49, lengthwise of which such collars may beadjusted and suitably fixed in. positions of adjustment. Each upperframe member ii? carries one of the rollers Thus there. are i'ourroller, two on each side of the nnu-hinc, for centering and stabilizingthe can or other object, indicated at (L in Fig. 5.

Stop means G may also be provided to limit the can or other device (1from play of movement lengthwise of the corrugating member B, that is,in a direction the reverse of that of the arrow in Fig. 1. Such stopmeans may comprise opposite stop plates or members 4&2 pivotallydepeinling from the frame iembers upon which the upper collars 4.0 ofthe members F and (l are mounted, each of such members 42 beingsimilarly provided with a collar 43, which collars surround said lastmentioned frame members. These members may be suitably held in positionsof adjustment endwise of the frame, so as to hold the can (A or otherdevice in proper position for suitable application and service of thecorrngating members A and B.

The lower shaft 8 has a bearing 8 at a point widely remote from theframe C, at the side opposite the journal means a, supported by bracearms 8" so that the shaft 8 is firmly sustained in such bearing S andthe bearing 1.1, and. sag at the free end of such shaft, namely. at theliiearing c, is prevented.

The operation, method of use and advantages of the corrugating machinefor cans and the like, constituting the invention. as

exemplified by the form thereof herein disclosed, will be readilyunderstood from the :foregoing description, taken in connection with theaccompanying drawings, and the followin statement:

In order to emplacc the can (/1 or other device to be corrugated uponthe lower (01'- rugating member B, the knock-down hearing or journal 0is thrown out of assemblage with the outer or free end of the shaft 8 byreleasing the latch 28, whereupon the weight 30 causes the lever members25 and 26% swing so that the members 25" and Q6 relatively separate andgive free access to the end of the shaft 8. Thereupon the can may fill.llll

stop means G, and between the means 1 for lower corrugatingmemberrugating members centering and stabilizing the can or other deviceupon the lower corrugating member. This of course is all done while theupper corrugating member A is s aced from the and after the can has beenbrought into position to be operated upon the hand wheel 23 is suitablyrotated to rotate the screw shafts 13 and 1a and cause the boxes 9 and10 to be lowered with the shaft 7, until the upper corrugating member Ais brought to bear upon the can, in workingrelation to the lowercorrugating member B. Just previously, the knockdown bearing 0 will havebeen reorganized by manipulating the handle member 29 to bring thebearing members 25 and 26 together, and latch the same by the lockingdevice or latch 28, so that the free end of the shaft 8 and suchknock-down bearing are assembled together operatively. Now, .ower

may be applied through the means 9 for jointly operating the corrugatingmembers, which latter will be revolved, roducing the operative effectindicated in 5, and resultantly corrugating or fiuting or creasing, orchanneling, or distorting or otherwise affecting the wall or surface ofthe can or other device, all in accordance with the specific nature ofthe dies or sections 31, and in accordance with the nature of the workand the effect to be produced upon the same. The adjusting means D maynow again be operated to elevate the screw shafts 13 and 14 with theboxes 9 and 10 and raise the upper shaft 7, so as to relatively separatethe cor- (after application of power through the means E has beenterminated and the knock-down hearing or journal 0 may be disassembledby unlocking the same at the latch 28, whereupon such bearing memberswill swing apart and open up again the free end of the lower shaft 8.The can or other object may now be removed from the lower corrugatingmember and is in finished corrugated condition.

It is evident that by this machine a can or the like may be formed upcompletely without alteration of the component material, such as sheetmetal, and after being brought into final can form or other form maythen be corrugated and fixed, as it were, in its completed form by thestrengthening or reinforcing incident to such corrugations or flutings.If the attempt be made to first corrugate the sheet metal or othermaterial entering into the construction of the can, and then form thecan, it will be necessary to operate in opposition to the obstructiveand preventive influences of such strengthening or reinforcingcorrugation or fiuting. Manifestly the proper time to perform suchfluting or corrugating is after the bending or workin of the canmaterial into its final form. The form of the can may in this manner bemost easily effected, and the resultant can may thus be stiffened into anon-yielding and reinforced and highly durable and stress resistingunit. Also, as it is customary to build a rim wire or edge wire intovarious cans and containers, at the open mouth thereof, and thisrequires for accurate work a true cylindrical or other formation of thecontainer mouth, it is much easier to accurately do this work when thecontainer has been formed up of undistorted or uncorrugated, orunchanneled material, inasmuch as such corrugation or distortion of thestock tends to prevent such true formation of the container. Inaccordance with the present invention, the container is formed ofuncorrugated material, and is formed into true and perfect shape,readily and truly receiving and being united with the rim ring or wire,prior to the corrugation of the completed container.

It is manifest that many changes and variations of the construction andinter-rcla tion and mode of operation of parts, members and features, indistinction from the foregoing description and statement and drawings,may be made in. adapting the in vention to varying conditions of use andservice, all without departing from the true spirit and essentialattributes of the invention.
